<H2 align="center">USE CASE 2: Verification of Installation </H2>
<p><B>Primary Actor:</B> Installer</p> 


<P><B>Stakeholders and Interests:<br>
</B>- Installer wants to run tests to verify the installation is successful.  </P>
<P><B>Preconditions:</B>
  <br>
  - Installer has finished the installation following README document. </P>

<P>
<B>Postconditions:</B>
<br>
- TraffoSim is verified to be correctly installed. </P>

<B>Main Success Scenario:</B>
<OL>
<LI>Installer launches TraffoSim. 
<LI>Installer checks the components on the interface being correctly initialized
  with the right default values.
<LI>Installer makes sure the configuration files are in place.
</OL>

<p><B>Alternative Scenarios:</B></p>
<p>&nbsp;&nbsp;1. TraffoSim cannot be launched correctly. <br>	 
  &nbsp;&nbsp;&nbsp;&nbsp;1a. A TraffoSim.log file is generated to show the cause
  (usually something wrong with the settings) and installer fixes the problem
  based on the error message.<br>
&nbsp;&nbsp;&nbsp;&nbsp;1b.  Nothing shows up (usually some necessary component,
like JRE, is missing) and installer re-install the system following the README
document. 
<BR>
</p>
<P><B>GUI Interaction:</B><BR> 
  The successfully launched TraffoSim should look like this:<br>
  <img src="images/case2.JPG" alt="TraffoSim Initialization" width="400" height="520"></P>
<P>
<B>Open Issues:</B><BR>
- Should automated ant task be included in the package for the purpose of verification
of installation? <BR>
